Updated 2021 MPG report

[Dlguzz]

It was not easy to find info on the gen 3 engine when I was making my purchase decision. So here are my results so far on the gen 3, 2nd year engine.

Order to delivery was 10 weeks.

'21 Bighorn, Crew cab, 4x4, 3.21 gears, 33 gal tank. All stock. So far, 3 trips with no load. Elevation 3-5k'. Temp mid 60's on all trips. 2 trips of approx 150 miles. 1 trip approx 300 miles. Ballpark trip mph overall is 55-65mph.
Trip 1=32mpg
Trip 2=31.5mpg
Trip 3=32.5mpg (longer trip)
Guage mpg and hand calculated matched every time after I topped off the tank.
So far, 1300 total miles on truck. No dash notification of any DEF usage. Def tank still shows full.

Hope this is helpful.

Thanks Dave!! I can agree and back you up on a 2020 4x4 Bighorn, completely stock. I did a 309 mile round trip today and rolled in at 31.1 on the dash, 31.02 by hand. All 65mph and under, back country roads in middle TN and southern KY. It was a pretty day and drive and I was about as easy as I could be on it.
